Insertion Tuning Fork Density Meter

China tuning fork density tester is a new product developed by our company.Fork Density Meters provide precision liquid density measurement in tank and pipeline applications. The Fork Density Meters use vibrating fork technology to measure density directly, and can be used in process control where density is the primary control parameter for the end product or as an indicator of another quality control parameter, such as %solids or %concentration.

1. Fork Density Meters provide precision liquid density measurement in tank and pipeline applications. The Fork Density
Meters use vibrating fork technology to measure density directly, and can be used in process control where density is the primary control parameter for the end product or as an indicator of another quality control parameter, such as %solids or %concentration.

2. Integral HART I/O direct input of external temperature, pressure, and flow measurements provide enhanced readings.

Features Tuning Fork Density Meters

1) Density is measured by frequency
    tuning fork vibration frequency in different media
    ² Vibration in the air, the frequency of about 1000 Hz ²
    Vibrate in oil at a frequency of about 700 Hz
    ² vibration in water, the frequency is about 600 Hz
    The density of the media determines the frequency of vibration

2)Rugged, accurate density and concentration measurement
  1. Continuous, real-time measurement in pipelines, bypass loops and tanks
   2. Accurate measurement of density (±1 kg/m3) and concentration (±0.1%)
   3. Wide range of corrosion-resistant materials for aggressive liquid measurement

3)Superior multi-variable I/O, meter health, and application capabilities
   4. Hazardous-area approved, head-mounted transmitter that supports local configuration and display
   5. Internal diagnostics for fast verification of meter health and Installation
   6. Application-specific factory configurations ensure fit-for-purpose operation

4)Installation flexibility and compatibility
   7. Optimized design – insensitive to vibration, temperature and pressure variations
   8.Unique direct insertion design in lengths of up to 13 ft (4 m)
   9. Supports multiple protocols for connection to DCS, PLC, and flow computers
  10. Optional stainless steel transmitter housing for corrosion resistance in harsh environment
